Homework Answers
When enough drying agent is added the solution becomes clear. When the solution is dry the drying agent does not clump together and floats freely around the flask when swirled.
Hence the correct statement is
A thin layer of particles that looks very similar to the orginal
particles moving around the flask when swirled.

Synthesis of n-Butyl Bromide Purpose of the Experiment: In this week's experiment you will be synthesizing n-butylbromide (IUPAC 1-bromobutane from 1-butanol and a concentrated acid via a nucleophilie substitution reaction. It is important to know that alcohols dehydrate to form alkenes in the presence of strong inorganic acids, so care must be taken in this experiment not to heat the reaction too vigorously else an elimination reaction may...

Hydroxide/Na2SO4 in Extraction? What does
each layer have inside in each step of the separation?
Please help. Due to corona, this is a theoretical lab and I am
very confused.

Introduction: The technique used to separate an organic compound from a mixture of compounds is called Extraction. Extraction process selectively dissolves one or more of the mixture compounds into a suitable solvent. The solution of these dissolved compounds is referred to as the Extract. Here the organic solvent dichloromethane is used to extract caffeine from an aqueous extract of tea leaves because caffeine is more soluble in dichloromethane (140 mg/ml) than it is in water (22 mg/ml). However, there are...
